Renewable energy comes from resources which are continually renewed by natural processes, such as sunlight, wind, rain, tides, and geothermal heat.

Renewable energy is potentially environmentally friendly, but not always. The "old" renewables, biomass and hydroelectricity, generally have massive negative impacts:

In 2006, about 18% of global final energy consumption came from renewables, but this is almost all from the old, damaging renewables: 13% from traditional biomass, mainly for heating, and 3% from hydroelectricity. "New" renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) accounted for only 2.4%, but are growing very rapidly.[verification needed]
